Quick answer

Do You Need a Site Plan for a Permit in Texas?

Yes, most building permits in Texas need a site plan: a scaled drawing of the lot, existing buildings and the new work, with distances to the property lines. Cities issue building permits inside their limits. Texas counties have limited building authority, so unincorporated areas often need only septic, floodplain or driveway permits, though HOA and deed rules still apply. We check that office’s requirements before quoting.
